Birds (last update September 2013) Philippa Horton, vs Inland Thornbills (Acanthiza pusilla and A. apicalis), have meant that in regions where these species abut Senior Collection Manager, Birds, or overlap some relatively arbitrary decisions have South Australian Museum been made to include certain records or not. Other species show seasonal or irregular dispersive movements Brian Blaylock, that are not yet reliably established or depicted on South Australian Museum; the maps. Finally, it should be noted that while the distribution maps are reasonably comprehensive, they Secretary, Birds SA do not include all records such as the numerous sight records in observers’ personal field books and others Andrew Black, that are not on any of the databases accessed for this Honorary Research Associate, list. There may also be some records that have been South Australian Museum accidentally overlooked. The maps give a good indication of where species The following list includes all species of birds reliably might be encountered routinely, but on rare occasions recorded as free-living forms from South Australia during any bird species may be seen well outside its known the period of European settlement.

In such instances the observer is non-passerines (of which seven are introduced) and 179 encouraged to contact Birds SA, SAM or DEWNR and passerines (six introduced), totalling 482 species for the to supply a description, and if possible photographs, so state. Appendix 1 at the end of this chapter includes: that the record can be assessed for possible inclusion in a) species for which records are unconfirmed or the BDBSA.

Maps Taxonomy and Nomenclature As in the first (Aslin 1985), second (Watts 1990) and Since the third edition (Robinson et al. 2000), a large third (Robinson et al. 2000) editions of this list, the volume of research, principally DNA-based, has distributional information (maps only in third edition) contributed to numerous changes in the taxonomy of has been compiled from several sources. These include Australian birds. The landmark work of Christidis and specimen data from the South Australian Museum, Boles (2008) summarised this research up to the time (SAM), and sight records from BirdLife Australia and from of its publication and we have used it as the basis for the SA Department of Environment, Water and Natural revising our list of SA species. Following Christidis and Resources (DEWNR), principally the Biological Database Boles (2008), the flow of newly published phylogenetic of South Australia (BDBSA), as detailed in the general and related studies has continued. We have assessed Introduction.

Morgan- Higher-level classification of birds continues to present Richards et al. (2008) tested the Metaves-Coronaves challenges but recent studies have resolved some hypothesis by analysing the complete mitochondrial major relationships. There is widespread agreement that genomes of 35 species including seven ‘metavian’ modern birds (subclass Neornithes) fall into two groups: species. They found these seven species separate into the Palaeognathae (ratites and tinamous) and the four different clades and there is no support for the Neognathae (all remaining groups), and that within the Metaves as a monophyletic group. They suggested Neognathae there is a major, early division between the that the high number of insertions/deletions within the Galloanserae (megapodes, pheasants, geese, ducks seventh intron of ß-fibrinogen resulted in artefacts during and allies) and all other birds – the Neoaves. analysis, while Mayr (2010) suggested this gene is subject to homoplasy (similarity arising from convergence). Several recent molecular studies have investigated Morgan-Richards et al. (2008) did not include parrots in relationships within the Neoaves.

They found into two groups: Metaves (caprimulgiforms, pigeons, a major diversification of at least 12 neoavian lineages flamingos, tropicbirds, swifts, hummingbirds, grebes and in the Late Cretaceous, with parrots possibly as a basal a few other small groups) and Coronaves (remaining split, falcons sister to a clade containing other diurnal groups). Ericson et al.

Christidis and Boles (2008) accordingly adopted this division with the result These studies plus others each provide a different that their sequence of orders is significantly different picture of neoavian phylogeny. Mayr (2010) made a from traditional classifications in placing tropicbirds, comprehensive review of morphological and molecular grebes, pigeons, caprimulgiforms and swifts in sequence studies and found that some neoavian groupings have between ducks and seabirds. widespread support (e.g. a sister relationship between owlet-nightjars and swifts with nightjars sister to both, Livezey and Zusi (2007) expressed concern that both and a close relationship between grebes and flamingos) molecular and morphological investigations were while for others their position remains uncertain (e.g. hampered by small character sets and limited taxon pigeons, and a clade containing caprimulgiforms, sampling. They made a phylogenetic analysis of 150 swifts, hummingbirds and allies).
